Understanding 70v systems
Jul 19, 2016 These systems often called 100V line or less common in Australia 70V line are found in most large buildings including shopping centres, schools, offices etc. These audio systems are typically used for general announcing, public address, background musicFeb 03, 2012 Other names are used to refer to these systems as well, including 70Volt Systems and Constant Power Systems. What truly differentiates a distributed audio system from a standard PA system is that transformers are built into the speakers and special amplifiers are used to power the speakers properly. understanding 70v systems
A constantvoltage or highimpedance audio distribution system is commonly used to overcome these and a number of other possible problems. These systems are also referred to by their nominal voltage, with 70Volt and 25Volt systems being the most common references.

May 23, 2016 This overview of the differences between 70V and 8ohm audio systems will help you understand which type to use and when. This overview of the differences between 70V and 8ohm audio systems
Constantvoltage speaker systems are also commonly referred to as 25, 70, 70. 7, or 100volt speaker systems; distributed speaker systems; or highimpedance speaker systems. In Canada and the US, they are most commonly referred to as 70volt speakers. In Europe, the 100 V system is the most widespread, with amplifier and speaker products
All About 70volt Speaker Systems. Almost everyone has hooked up a speaker to an amplifier. Two wires from each speaker to two terminals on your amplifier or receiver.
connecting speaker systems in a 25v 70v 100v constant voltage distribution systems. 25v 70v 100v systems are typically used for paging, telephony, background music and other multiple inputs, where high sound volume or even, sometimes, the quality of sound is not the main consideration.
You're interested in setting up your own commercial speakers (otherwise known as a 70 volt speaker system) and need some help understanding the process? I didn't know where to start recently when my company was moving offices. We didn't include the 70v speaker system in the lease and there was nothing in the new location. Being that our company
Understanding Distributed Speaker Systems. I am trying to calculate the impedance of a ceiling speaker Tannoy CVS6 on which the rotary switch shows 70V and 100V and at certain positions the dots on the speaker indicate both 70V and 100V (half power). Articles on Understanding Audio. Understanding Distributed Speaker Systems.
Jun 01, 2015 Understanding outdoor speaker wiring. Date June 1, 2015. You can get great sounding 70V speaker systems many restaurants and bars use 70V systems. The physics of higher voltages means that long speaker wires are much less of an issue at 70V, so you can run very long wires if needed. The 70V is stepped down to regular speaker voltage by
